How Do Snails Leave Dotted Trails?

If we humans had this ability you could effectively lay a trail. There are lots of different theories I've read about why one is that there's a kind of snow called the rosy wolf snail which is a predator snail and it hunts other snails by their trails. They just proceed without making every bit of the idea that they're leaving gaps so that people can't follow themYes cool idea because there was a thing wasn't there in last year in the news where they found some someone was smuggling snails in an airport or something yes  and they found one snail Yes and they just followed his snail trail back they found like a hundred more or something wow these giant African land snails
